Dr. Anthony Fauci says the White House Coronavirus Task Force is working around the clock to fight the coronavirus outbreak in an interview with Mark Levin on FNC's 'Life, Liberty & Levin.' Fauci said Trump has never challenged him on the science of coronavirus on 'Life, Liberty & Levin.'

MARK LEVIN: Welcome back. Dr. Fauci, let me ask you a question. You've been doing this a long time. Have you ever seen this big of a coordinated response by an administration to such a threat? A health threat?

DR. ANTHONY FAUCI: Well, we've never had a threat like this and the coordinated response has been, there are a number of adjectives to describe it. Impressive, I think is one of them.

I mean, we're talking about all-hands on-deck is that I, as one of many people on a team, I'm not the only person, since the beginning that we even recognized what this was. I have been devoting almost full time on this -- almost full time.

I'm down at the White House virtually every day with the Taskforce. I'm connected by phone throughout the day and into the night and when I say night, I'm talking twelve, one, two in the morning. I'm not the only one. There's a whole group of us that are doing that. It's every single day.

So I can't imagine that that under any circumstances that anybody could be doing more. I mean, obviously, we're fighting a formidable enemy -- this virus. This virus is a serious issue here.

Take a look at what it's done to China, to Europe, to South Korea. It is serious and our response is aimed, and I know you've heard that many, many times, and this is true. I mean, I deal with viruses my entire career.

When you have an outbreak virus, if you leave it to its own devices, it will peak up and then come back down. What we learned from China, that letting it peak up is really bad, because it can do some serious damage. So we are focused now, like a laser on doing whatever we can, and there are two or three things that deserve to be mentioned -- to make this peak actually be a mound, which means you're going to have suffering, you're going to have illness, you're going to have death. But it's not going to be the maximum that the virus can do.

A couple of ways to do that. The first was, as we say, all the time, the very timely decision on the part of the President to shut off travel from China, because we saw that there was this possibility of people coming in and seeding in the country. We did it early.

And as it turned out, there were relatively few cases in the big picture of things that came in from China. Unfortunately, for our colleagues, and many of whom are my friends and people I've trained actually in Medicine, in European countries, they didn't do that. And they got hit really hard and are being hit really hard. The first thing.

Second thing, when the infection burden shifted from China to Europe, we did the same thing with Europe. We shut off travel from Europe, which again was another safeguard to prevent influx from without in.

The other way you do it is by containment and mitigation. And now everybody knows what the word mitigation means because it's the things that we're doing. No crowds, work from home. Don't go to places that you can be susceptible. Ten people in a room, not 50 and a hundred people. Stay away from theatres.

Take the elderly people who are susceptible and have them do self- isolation. Stay out of bars, stay out of restaurants.

If you're in an area where there's a lot of coronavirus activity, close the bars, close the restaurants. That's heavy duty mitigation.

So I think with all of those things going on at the same time, I believe we will -- we're already doing it, but you just can't notice it yet because you have the dynamics of the virus going up. We're trying to put it down. You're not really sure quantitatively what you're doing, but you can be actually certain that we're having an impact on it.
